Instant 404 Smart Fixer

Instant 404 Smart Fixer is a lightweight, high-performance plugin designed to recover lost traffic from broken links. instead of showing a generic 404 error page, it intelligently searches your existing content for a match and redirects the user automatically.

Key Features:

• Smart Match Algorithm: Extracts keywords from the 404 URL and searches for matching Posts, Pages, or Custom Post Types with >80% similarity.
• High Performance: Uses optimized WP_Query calls and WordPress Transients API to cache redirect decisions for 24 hours, ensuring zero impact on server load for repeated hits.
• Zero Bloat: Built with a focus on speed and simplicity. No heavy frameworks or unnecessary database tables.
• Admin Logging: View the last 10 redirect events in the settings page to see exactly what the plugin is doing.
• Privacy Focused: Does not track user data, only logs the URL string for debugging purposes.

How it works:

1. A user visits a broken URL (e.g., /my-amsome-post).
2. The plugin detects the 404.
3. It searches for a post with a similar title (e.g., “My Awesome Post”).
4. If a match is found, it performs a 301 Permanent Redirect to the correct post.
5. If no match is found, it redirects to the Homepage (302) to keep the user on the site.
